Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for treating textile products such as knitted fabrics, woven fabrics, non-woven fabrics, and yarns with low-temperature plasma.

Conventional means for performing treatments (pretreatment) such as desizing and scouring on industrially produced knitted fabrics, woven fabrics, threads, etc.
For example, it is well known to perform moist heat treatment using large amounts of thermal resources, water sources, or specific chemicals under high pressure or normal pressure. To describe an example of this well-known pretreatment in detail, for example, a fabric to be treated is impregnated with a treatment solution made by mixing a caustic solution with a penetrant, etc., and is steamed in a reaction chamber under normal pressure or high pressure. The reaction with the chemical solution is continued for a predetermined period of time to complete the pretreatment, and then washing with water is repeated as a means to remove the chemical solution or impurities adhering to the fabric to be treated. The fabric to be treated was dried by passing it through a dryer, and the target pre-treatment in item (9) had been completed. On the contrary, such pretreatment means require a chemical solution for treatment and a large amount of steam to react with the chemical solution on the fabric. A large number of washing machines are required to remove residual liquids and impurities from the fabric, and a large amount of water is required to be supplied to each of these washing machines. At present, a large amount of water resources and thermal energy are consumed to completely pre-treat the fabric, as equipment for disposing of the liquid is required. Furthermore, since the waste liquid discharged from washing machines inevitably contains chemicals, problems such as waste liquid pollution arise, and processing of the waste liquid also requires significant equipment and personnel costs. However, it was not economical, especially in textile processing.

The present invention has been made in view of the above, and provides a treatment method and apparatus that can pre-treat (scouring, etc.) textile products such as fabrics and threads without using almost any thermal energy or water source. It provides: That is, to describe the present invention specifically, low-temperature plasma is applied to the fiber surface and inner core of the four-layer textile product to be treated, and water-repellent contaminants attached to the fiber surface and between the fibers are removed. By oxidative decomposition or by converting impurities into water-soluble compounds to make them hydrophilic, treatment effects such as scouring that particularly reach the inner core of the fibers can be effectively carried out. A treatment method and device that can economically process the surface and inner core of textile products such as scouring (hydrophilization treatment, etc.) without using water resources, and without causing pollution problems due to waste liquid. The purpose is to provide the following.

The present invention will be explained in detail below based on embodiments shown in the drawings.

Example ■ In Figures 1 and 2, this example uses a fabric as a product, 1 is a reactor, and this reactor 1 is with y<Aa
An opening 4 is provided 7' for taking in and out the textile product 3 wound up on the A-product winding/matrix 2, that is, the perforated beam, and this opening is sealed with a lid 5. Furthermore, inside this reactor 1, there is a winding pipe 2.
a rail 7 that guides a trolley 6 that supports the winder 9;
A large number (four in this embodiment) of electrode plates 8 are installed close to the textile product 3 wound around the web 2. In order to obtain this, it is formed of, for example, a connecting metal with a large number of through holes, a wire mesh, or the like. Reference numeral 9 indicates a gas supply 1 to be supplied into the reactor 1, and 10 indicates a vacuum pipe that penetrates the inside and outside of the reactor.
The reactor-side tip of the mu-guizo is connected airtightly to the inside of the winding pipe f2.

The configuration of the apparatus according to this embodiment has been described above. Next, a method for processing textile products, that is, fabric 3, using this apparatus will be described. The textile products applied to this treatment are cotton 10
0%, or mixed woven or mixed knitted fabric made by mixing cotton with delicate materials such as polyester fiber, vinylon, nylon, wool, (5) hemp/sheath, ace "j-", L/-yon, etc. Must 9, this IJ hanging 3
Wrap a suitable i (appropriate length) on the winding pipe 2, and then attach 41 + hanging 3 attached to the winding pipe to the bogie 6.
The winding pipe f is also connected to the vacuum pipe flO. Thereafter, the reactor 1 is hermetically sealed, and a vacuum bomb f (not shown) connected to the vacuum via "10" is fully operated to reduce the pressure inside the reactor 1 to reduce the degree of vacuum to I Torr or less, preferably 0.
By supplying a predetermined gas into the reactor 1 through the temporary gas supply port 9, which is set to 5 Torr or less, and adjusting the exhaust volume and gas supply amount by the vacuum pump, the degree of vacuum in the reactor l can be adjusted to fco.
, 1 to 10 Torr or 0.5 to 2 Torr
Adjust to r. In addition, this A-air condition is 0.1 to 10 Tor.
The reason for limiting the rVC is that when the degree of vacuum is less than 10 Torr, the generation of low-temperature plasma (described later) becomes unstable, and
, Maintaining the degree of vacuum below 1 Torr not only increases equipment costs, maintenance, and operation costs in terms of vacuum bomb f capacity and seal @'rs, but also reduces the low-temperature glazma gas degree (a'X). This is because the processing effect also decreases.

After adjusting the vacuum inside the reactor 1 to a vacuum level of )) Jl with a predetermined gas, the electrode plate 8 is heated with a high frequency, preferably 1 k.
Apply high frequency power within the range of I4z to 300 Mflz. Therefore, when a high frequency is applied to the electrode plate 8, a low-temperature plasma is generated between this electrode plate and the grounded winding wire, that is, within the reactor 1.

In this way, when 100% oxygen or a mixed gas containing enzymes supplied into the reactor 1 under a reduced pressure of 01 to 10 Torr is irradiated with high frequency, the oxygen molecules are excited and low-temperature plasma is generated. When suction from Bakiem 9 Ino 10 is continued, the low temperature plasma inside the reactor will
Due to the negative pressure inside the winding web 2, the inner core of the wound fabric is permeated and absorbed into the IJ fabric 3 that is wound around the winding web 2. The low-temperature plasma acts on the fabric, and as a result, impurities contained in the fabric are oxidized and decomposed or converted into compounds that easily dissolve in water, greatly improving the hydrophilicity and permeability of the fabric. The fabric obtained is as follows.

Example ■ In Figures 3 and 4, this example deals with processing yarn, ie, cheese, as a textile product. The breathable material 2' is held upright by the support 11, and each breathable material 2' is made of 100% cotton or cotton, such as polynisdel fiber, vinylon, nylon, wool, linen, silk. A plurality of cheeses 3', which are blended yarns or intertwisted yarns made by mixing fibers such as acetate, rayon, etc., are stacked on top and bottom in large numbers. Other structures are @
Implementation? tl, 4 is the opening of the reactor 1', 5 is its lid, 8' is an electrode rod arranged around the cheese 3', 9 is a gas supply port, and 10 is each ventilation pipe 2. It is a vacuum/guive that communicates with the inside of '. Therefore, in this example, as in the above embodiment, the pressure inside the reactor 1' was once reduced to 0.1 to 0.5 Torr, and then gas was supplied through the gas supply port 9). So, this reactor 1
The pressure is adjusted to approximately 0.5 to 10 Torr, and a low-temperature plasma is generated within the reactor 1 by applying a frequency t to the electrode rod 8'. Furthermore, if suction by Paquim Seven If 010 is continued, the low temperature plasma inside the reactor will become breathable! Due to the negative pressure inside 2', its breathability and Inno2
The low-temperature plasma acts on the fibers of the cheese 3' located around the threads, and as a result, impurities attached to or contained in the threads are oxidized and decomposed or converted into compounds that easily dissolve in water, making them hydrophilic. This results in yarns with significantly improved permeability.

Incidentally, the winding 147, f2 and air permeability A, 02/ in each of the above embodiments may be rotated within the reactors 1 and 1', and this rotating action applies a uniform force to the entire circumference of the textile product. It becomes easier to perform low-temperature plasma treatment.

As described above, the present invention provides 11 plants 1 which are wound and held in a permeable porous pipe and are placed in a hot plasma generating atmosphere, and then the porous pipes are ．． - Since the low-temperature plasma is connected to the coffin structure and penetrates into the coffin product, the present invention also removes core impurities in the inner core of textile products such as fabrics and threads. The low-temperature plasma converts the chemical component W4 into a compound that easily dissolves in water, and removes impurities on the surface and inner core of the four-cut fiber product. That is, the greatest feature of the present invention is the winding mechanism connected to the vacuum pipe.
By winding a long textile product around the pipe 2 and placing the textile product in a low-temperature plasma atmosphere inside the reactor, negative pressure inside the reactor is maintained through the winding shaft. Because of this, the low-temperature plasma in the reactor is applied to the inner core of the textile product being wound due to the negative pressure action (suction action) through the winding and mother eaves. The low-temperature plasma acts on the inner core of the coffin fPJk product, and as a result, the low-temperature plasma treatment is performed not only on the surface of the 4JR textile product but also on the inner core, resulting in high-quality low-temperature plasma treatment, that is, fine A-Hot. It is necessary to have an effect that allows processing such as. Historically, the present invention is capable of low-temperature plasma treatment of a large number of non-woven fabric products at once in a reactor, thereby increasing treatment efficiency, ie, productivity.

According to the present invention, by infiltrating the first generation temperature glazma into the rectangular surface, pretreatment including desizing is possible without using P1 thermal energy, water scraping, or leftover liquid. Therefore, the pretreatment of textile products can be carried out economically and quickly without causing any damage to the waste liquid.
